IQADA00 Single/Dual-Channel Analog DA

The IQADA00 provides dual analog inputs with up to five outputs per input, or a single analog input with up to ten outputs.

FEATURES

  • Configurable for one input to ten outputs, or two inputs to five outputs per input (dependant on rear panel type)
  • Very low THD+N
  • Output gain remotely adjustable from +24 dB to -24 dB with fine control
  • +24 dBu headroom

SPECIFICATIONS

Inputs and Outputs

Signal Inputs
Analog: 2 channels balanced via screw-terminal or D-type connector

Signal Outputs
Analog: 4 (5) per input channel balanced via screw-terminal (or D-type connector)
Note: Configurable for 1 input to 8 (10) output operation

Card Edge and RollCall Controls

Indicators
Power up or CPU fault: Good = Off/Fault = Red

CPU running but input 1 not detected (both inputs or primary input when in single channel mode): Input detected = Off/Not Detected = Yellow

CPU running but input 2 not detected (both inputs or primary input when in single channel mode): Input detected = Off/Not detected = Yellow

Normal operation with input detected (either input or primary input when in single channel mode): Input not detected = Off/Input detected = Green

Controls
Mode: Single, Dual channel

Fine gain adjustment: ±0.5 dB additional to the coarse gain level, separately adjustable for each input

Functions Available via RollCall
Gain (separate L and R): +24 dB to -24 dB in 0.5 dB steps

Silence detect: Level adjustable, -15 to -25 dBu in 1 dB steps

Warning timer: 1 to 60s (for silence detection)

Logging
Input x State: OK, WARN Silence (L and R)

RollTrack controls: On/Off, Index, Source, Address, Command, Status, Sending

RollTrack:

  • Unused
  • Input 1Present
  • Input 1 Silent
  • Input 2 Present
  • Input 2 Silent
  • Input 2 Silent
